I have successfully create a replica between 2 geodatabase and use a scheduler to synchronize the replica between the 2 geodatabase several months ago. But the scheduler didn't work because of changes in the original geodb. In this case I need to create the replica once again (according to user's request), my question is if I use the same replica name, is there a need of deleting the existing one? What will happen if I create the replica directly? Any potential dangers? Since this is a in operation system, I cannot afford of failure.
EDIT: After my research from internet, I even cannot find a way to delete a replica.
